Lessons learnt in Switzerland

17 million of certified MINERGIE

®

-Buildings have a

value of 50 billion CHF and 7 million m

2

total surface

of buildings in MINERGIE-Standard, not certified

Reduced energy consumption by 130 mill. Liter

oil-equivalent/year

Higher value of buildings from 3% (condominiums) to

6% (single family houses)

Awaken the economical interest of the industry in

energy efficient products

Set-up the largest Swiss training organization in

building sector

Increased building industry by 8‘500 jobs (3%)

(18)

The Reasons behind the MINERGIE

®

Success

Clear, simple and voluntary building standard

Broad national, state and local support in political and

business circles, as also in trade and professional

associations

First of all: comfort in the home and at workplace;

secondly, lower energy bills

A clear and consistent brand strategy

State application and certification

Professional networking

MINERGIE-Label for comfortable und highly

energy-efficient buildings in India?

Let us make use of Swiss knowledge and experience

and explore how the successful model and technology

of

MINERGIE

may be transferred to a similar

organization in India and adapt the standards to the

different Indian climate zones.
